Without doubt Air Manager is one of the best products released to the masses 
The FIPS have their purpose though if you already have them; browse through those gauges and even with a small screen you can do some great things in your cockpit. Some designs can function really well for CAS, Annunciators, Emergency, Warnings, and many more…I just like the fact that it’s a whole package with encoder, button and screen that is already programmed and very functional.
